## Summary
Fixes a segfault that occurred when calling `process.dlopen` with
`null`, `undefined`, or primitive values for `exports`.
Previously, this would cause a crash at address `0x00000000` in
`node_module_register` due to dereferencing an uninitialized
`strongExportsObject`.
## Changes
- Modified `src/bun.js/bindings/v8/node.cpp` to use JSC's `toObject()`
instead of manual type checking
- This matches Node.js `ToObject()` behavior:
- Throws `TypeError` for `null`/`undefined`
- Creates wrapper objects for primitives
- Preserves existing objects
## Test Plan
Added `test/js/node/process/dlopen-non-object-exports.test.ts` with
three test cases:
- Null exports (should throw)
- Undefined exports (should throw)
- Primitive exports (should create wrapper)
All tests pass with the fix.
## Related Issue
Fixes the first bug discovered in the segfault investigation.
